Application'led March 7, 19011.Y Serial N. 196,955. (No model.)

To @ZZ u'tom it may concern.-

Be it known that l, HENRY L. GERKEN, a citizen oi' the United States, and a resident of the city ot New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Valve Mechanism, oi' which the following is a full, cleark and exact description. f

This invention relates particularlyT to improvements in valves and distributing mechanism for radiators, the object being' to provide a valve of simple construction and positive in its operation that will permita supply of steani, hot water, or refrigerating liquid to one or more divisions of a radiator or to one or more radiators at will.

l will describe a valve mechanism embodying my invention and then pointout the novel features in the appended claims. V

Reference is to be had to the accompanying drawing's, forming' a part of this speciiication, in which similar characters of reference indicate corresponding' parts in all the figures.

Figure 1 is a sectional elevation ot' a radiator and valve mechanism embodying my invention. Fig. 2 is a sectional elevation thereof, showing' a modiiication; and Fig. 3 is a side elevation showing features of Figs. 1` and 2. A

The radiator comprises vertical circulating'- tubes divided into sections A B by means, as here shown, of a partition C. At one end oi' the radiator is a valve-casing" 1, divided into lower and upper chambers 2 3. The chamber 2 communicates with an inlet 4 through an opening 5, around which is a valve-seat 6, and the chamber 2 communicates with the chamber 3 through' an opening 7,'having an annular valve-seat 8. For engaging with the valve-seat 6 I employ a valve 9, and a valve 10, which is cup-shaped, is designed to engage with the seat 8.

Having' rotary connection with the valve 9 is a stem 11, the said stem passing' through a suitable stuffing-box 12,. carried on the valve 10, and the threaded portion 13 of 'the stem 11 engages with a thread in the hood 1,41.

The valve-chamber 2 communicates. with the section A oil the radiator through a pipe 15, the two tubes of said section A communieating one with the other through a passage 16. Y The upper chamber 3 of the valve-casing communicates with the section B through a pipe 17. which passes through the pipe 15 and also through the opening' or passage 16, and the two tubes of the section B communicateV through a passage 18. While I have shown but two tubesin each section, it is to be understood that my invention is not limited to any particular number of tubes in a section or to the particular construction lot' radiator shown. The valve 10l is held yieldingly against its seat by means of a spring 19, which engages on the upper side of the said valve and also engages with the hood la.

In the operation when it is desired to pass the heating medium to one section of the radiator`the valve 9v is to be raised from its seat, opening communication between the inlet and the chamber 2. The heating medium of course will pass into this chamber and thence into the section A of the radiator. itis desired to heat both sections of the radiator, the stem 11 is to be turned so that the valve 9 will engage with the valve 10 and move it upward from its seat against the resistance ot' the spring' 19. `Obviously the heating medium will then pass through the pipe 17 into the section B, and the heating' medium will also pass into the section A. By turning the stem 11 down it is obvious thatthe valve lO'will be forced against its seat by ,meansV oi." the spring, and by the continued downward movement oi' the stem the valve 9 will bek caused to be seated, thus preventing the entrance ot' heating medium to either section of the radiator, suitable air-valves of course being provided for each section.

In Fig.'2 thetwo sections A B are separated atthe lower portion by means of a solid partition C. In this example of my improvement a supply-pipe 20 leads from the chamber 2falong the outer or under side ofthe radiator and communicates with the section B oi' the radiator, while from the chamber 3 a pipe 21 leads intothe section A.

In Fig. 2 the upper portions of the tubes lof the radiator are connected one with another by short tubes so that there can be a free circulation ot liquid or the like, and this upper portion is provided with an airvalvc 2S), and a supply or return pipe 2a also communicates with the upper sections ot' the radiator. rlhis is designed particularly for refrigerating or for hot-water heating, and consequently both supply and return pipes will be required.

The operation is as follows: First, if used as a supply-valve connect the return-pipe at either end ot' or elsewhere on the upper part of the radiator, and the valve will then operate practically as in Fig'. l, supplying liquid in place of steam, which will pass oli' through the return-pipe 24, thus cooling' or heating the part or parts through which thecirculation is permitted to pass. This method of connections will be found preferable for retrigerating systems. Second, if used as a return-valve connect the supply-pipe 24 at either end or elsewhere on the upper part of the radiator and connect the lower divisions ot the radiator to the different parts of the valve, as shown in Fig. 2. By raising the valve 9 a circulation will start in division B, and by a further movement the valve 10 is raised. A circulation will then start throug'h the division A, thus using the entire radiator, and so heating or cooling' the part or parts through which the circulation is taking' place.

Having thus described my invention, l claim as new and desire to secure by Letters Patent l. A radiator comprising two sections, a valve-casing having two chambers communicating' one with the other and communicating with an inlet, a pipe connection between one chamber or' the valve-casing' and one section of the radiator, a pipe connection between the other chamber ot' the valve-casing with the other section ot' the radiator, and valves Jfor controlling the communication between the inlet and chambers and for controlling the communication between the chambers, and a single stem for operating both valves.

2. A radiator comprising separated sections, a valve-easing comprising a lower chamber and an upperchamber, a pipe leading' from the lower chamber to one section of the radiator, a pipe leading' Vfrom the upper chamber to the other section ot' the radiator, the said two chambers communicating' one with the other, and the lowerehamber communicating with the inlet, a valve tor controlling the communication between the two chambers, a valve for controlling thc inlet, a stem extended from said inlet-controlling valve loosely through the firstnamed valve, and a spring' for holding' the first-named valve yielding'ly against its seat.

3. A radiator comprising two separated sections, a valve-easing' arranged at one end of the radiator and comprising lower and upper chambers, an inlet having communication with the lower chamber and the said lower chamber communicating with the upper chamber, a valve for controlling the inlet, a valve for controlling the communication between the two chambers, a stem extended from the inlet-controlling valve loosely through the second-named valve, a thread on said stem, and a hood on the val ve-casing having' a threaded opening for receiving the thread oi' the stem.

et. A radiator comprising' separated seetions` a valve-casing having lower and upper chambers communicating' one with the other, the lower chamber communicating with an inlet, a pipe leading from the upper chamber into one section of the radiator, a pipe leading from the other chamber through the lirstnamed pipe and into the other section of the radiator, a valve for controlling the inlet, a valve for controlling the communication between the two chambers, a stem extended from the first-named valve through the lastnamed valve and having' a threaded portion for engaging' in a threaded portion of the casing-hood, and a spring' for holding the lastnamed Valve yieldingly on its seat.`

5. A radiator comprising two separated sections, a valve-easing having a lower and an upper chamber, the said chambers communicating one with the other, an inlet having communication with the lower chamber, a pipe leading from one chamber into one seetion ot the radiator, a pipe leading from the other chamber into the other section of the radiator, a valve for controlling the inlet, an inverted cup-shaped valve for controlling' the communication between the two chambers, the said valve being adapted to receive the lirst-named valve, a stem extended from the inlet or outlet controlling' valve loosely through the cup-shaped valve and having screw-threaded engagement with the valvecasing, and a spring for holding the cupshaped valve yieldingly on its seat.

1n testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
